Supply

This note is about the concept of supply, especially heterogenous or multi-modal supply of habitat structures by biological and artificial systems.

Definition

Supply of habitat is a function or a service provided by some members of an ecosystem to other members.

This word is useful because it emphasises the active provisioning of a resource and links different modes of provisioning.

Related terms:

provision of ecosystem services (such as habitat provision, biologically generated habitat provision)
improvement of habitat quality
habitat availability (sounds passive by contrast)
ecological services (ES) supply maps
resource supply (e.g., cf. supply/demand in population ecology) 1
resource use efficiency 2
processing chain ecology 3

Relevant terms:

supply chain

The amount of a good or a service available to consumers. Or the quantity of a commodity that a supplier is able and willing to sell.

Supply of perch branches, cf. Perches
Supply of hollows ("when the harvest rotation time is 100 years or less, a supply of trees with hollows cannot be ensured by only retaining trees which already have hollows")
